Donald Woods reassigned GERONIMO-5553:
--------------------------------------

    Assignee: Rick McGuire  (was: Donald Woods)

Both of these are registering transformers -
openjpa2/geronimo-aries-jpa/src/main/java/org/apache/geronimo/aries/jpa/GeronimoPersistenceUnitInfo.java
openjpa2/geronimo-persistence-jpa20/src/main/java/org/apache/geronimo/persistence/PersistenceUnitGBean.java

So, are all WAR files being turned into WAB files and run as OSGi bundles in 
3.0?  If so, then using JPA in WAR files is going to require Aries and the 
geronimo-aries-jpa code, which knows about bundle context, while the normal 
geronimo-persistence-jpa20 code has no knowledge of bundles and how to access 
their classloaders???
